Answer 1

4 inches represents (50) miles How many inches would represent 125 miles 4 times 1 inch = (50) miles 1 inch = (50)/4 miles x inches = 125 miles x times (50 /4) miles = 125 miles [x = 4 times 125/50 = 500 /50 = 10] [Therefore 10 inches represents 125 miles.] Franciso ran for 35 miles alpha be walked for 6 miles & Fransisco runs hour faster than he walks & if it look him 7 hours to finish the race let walk speed x miles spectrum run speed = (x + 4) miles per hour we know that v = D/T (distance . time D = VT he ran for 35 miles with speed (x + 1) mph D_1 = V_ 1 T_1 35 = (x + 4) t_1 t_1 = 35/x + 4 the walked for 6 miles with speed x mph D_2 = v_2 t_2 6 = x t_2 t_2 = 6/x alpha he covered (35 + 6) miles be took
