Question

Answer the following questions: 1. Tenzin was fishing and caught a sailfish, which took out 90 metres of line in 3 seconds. How fast was the sailfish swimming in km per hour? 2. Gretchen measured the square lid of a box very precisely and calculated the area as 64,516 square mm. What is the area in square inches?

need help in solving these mathematical problems for an assignment.

Answer 1

0 I hour = 60 minutes = 60x60 Seconds that is Thous = 3600 Seconds | Second = 5 I kilometer = 1000 meters I metre = to Kilometers hours 3600 Speed of (now change to Kilometers) od is 90 meters per 3 Seconds = 30 meters per second | Kilometers per second = 3 kilometers per second change Seconds to hows speed 2000 hours . = 3 kilometers per now Calculate the speed in 1 hour 100 = 3x3600 Kilometer per hour = 108 kilometers ber hou. per hour speed of Sailfish = 108 km

0 Area of the lid = 64,516 Square mm we know I inch 25.4 millimetres 1 Square inch = 1 inch x I inch = 25.4 mm X 25.4 mm = 645.16 (mm)? 1 Squale inch = 645.16 Squale mm I square mm = Squale inch b 645.16 given alea = 64,516 Square mm = 64,516 caria Squale inch = 100 square inch
