Question

Calculate the time taken by a car travelling at a speed of 10m/s to travel a distance of 72km

Answer 1

Answer:

2 hours

Explanation:

Given that,

a car travelling at a speed of 10m/s

here,

initial velocity of the car = 10 m/s

now, here,

given

total distance travelled by the car

= 72 km

= 72 × 1000 m

= 72000 m

now,

we have,

velocity(u) = 10 m/s

distance travelled (S) = 72000 m

we know that,

time taken =

total distance travelled/velocity

= 72000/10

= 7200 s

= 2 hours

so,

the time taken by a car travelling at a speed of 10m/s to travel a distance of 72km

= 2 hours

Answer 2

Answer:

2 hours

Explanation:

given,

total distance travelled by the car

= 72 km

= 72000 m

now,

speed = 10 m/s

distance travelled (S) = 72000 m

time taken =

distance covered/speed

= 72000/10

= 7200 s

= 2 hours

so,

time taken = 2 hours
