Question

Numerical: [2+2+2]

a. If a car travels 5 km in 30 minutes, calculate the speed of the car in km/h unit.

b. If a train travels 185 km with 45 km/h speed, calculate the time taken by the

train to travel that distance?

c. How far an object will go in 95 s with 12.5 m/s speed?​

Answer 1

Explanation:

for A

v = d/t

= 5/0.5 (1 hr=60 min then 30 min =1/2 hr)

=10km/h

for B

v =d/t

t = d/v

= 185/45

= 4.1 hr

For C

v=d/t

d=vt

= 12.5 ×95

=1187.5 m
