sally runs 5km in 25 minutes. she plans to run in 20 km race. based on the current speed how long will it take her to complete the race?

Given:

Sally runs 5km in 25 minutes.

Total distance of race = 20 km

To find:

How long will it take her to complete the race?

Solution:

We have,

Time taken by Sally for 5 km = 25 minutes

Time taken by Sally for 1 km = minutes

                                               = 5 minutes

Time taken by Sally for 20 km = minutes

                                               = 100 minutes

                                               = 1 h 40 minutes               [ 1 h = 60 min]

Therefore, the time taken by Sally to complete the race is 1 h 40 minutes.
