Question

Write a program that calculates the time Alonso took between two given laps during his race at the 2018 United States Grand Prix (Austin, TX). The race consists of 56 laps (191.6 miles) in a closed loop circuit. Alonso started well and drove at 215 mph for the first 12 laps. After that, he experienced some problems with the gas intake valve and drove at 197 mph for the next 17 laps. Then, he forgot to change the tires and lost a lot of traction, so he drove at 164 mph for the next 14 laps. Finally, he remembered to turn on the KERS system and gained some speed so he drove at 208 mph for the last 13 laps. Unfortunately, this didn't help much since Alonso finished the race by himself while the rest of the drivers were already at the press conference. Your program should be given an initial lap and a final lap and it should calculate the time Alonso took to go from that initial lap to the final one. Each lap at this track has 3.426 miles. Speed (mph) Laps 0-12 215 12-29 197 29-43 164 43-56 208

plz explain using matlab

Answer 1

here I have converted each lap to there corresponding time

example

for 1st lap 0 to 1

t(1) is their corresponding time

and addition of times between that lap has been done

example for the time between 14 to 18 lap

will time for 15,16,17 and 18th lap

%program
clc
clear all
a=input('enter the initial lap : ');
b=input('enter the final lap:');
dis_one=3.426; %dis_one = distance in miles for one lap
n=b-a; %number of laps
d=dis_one*n; %distance covered in total
%loop for velocity matrix and corresponding time (seconds) matrix for each lap
for i=1:56
if i<=12
v(i)=215;
t(i)=dis_one*3600/v(i);
elseif i<=29
v(i)=197;
t(i)=dis_one*3600/v(i);
elseif i<=43
v(i)=164;
t(i)=dis_one*3600/v(i);
else
v(i)=208;
t(i)=dis_one*3600/v(i);
end
end
if a-b==0
total_time=t(a);
end
for i=a+1:b
total_time(i)=t(i);
end
time=sum(total_time)
