Question

Rohit travelled a distance of 117 miles in 2.25 hours to reach home. Find his average speed (in metre/second) (1 mile=1.609344)

Answer 1

1 mile = 1.609344 km
117 miles = 1.609344*117=198.13km
but I km =1000m
198.13 km = 198132.48 m

now I hour =60 min =3600 seconds
2.25 hour = 3600 X 2.25=8100sec
average speed = total distance / total time taken

s = 198132.48m / 8100 s
s= 24.46 ms-¹
