Question

A car is travelling with a speed of 80 km/h. It has travelled for 5 hours with the same speed. Calculate the distance it has travelled in 5 hours. Write your answer in km as well as in m.


please answer ​

Answer 1

ProvidEd that:

• Speed = 80 kmph
• Time taken = 5 hours

To calculate:

• The distance

Solution:

• The distance in km = 400
• The distance in m = 399960

Using concept:

• Formula to find distance

Using formula:

• Distance = Speed × Time

Required solution:

Calculating in kilometres

→ Distance = Speed × Time

→ Distance = 80 × 5

→ Distance = 400 kilometres

Calculating in metres

~ Firstly let us convert 80 kmph-mps

→ 80 × 5/18

→ 400/18

→ 22.22 mps

~ Now let's convert hours into seconds

→ 1 hr = 3600 seconds

→ 5 hr = 3600 × 5

→ 18000 seconds

~ Now let's calculate distance

→ Distance = Speed × Time

→ Distance = 22.22 × 18000

→ Distance = 399960 metres $\:$
