How much time will you save on a ten mile trip if you travel at 60mph rather than at 55mph?

Solution:

Consider the speed 60 mph as s₁, and the speed 55 mph as s₂.

Now, we have

Time = distance / speed

Given distance = d

= 10 miles

t₁ = 10 / s₁

= (10/60) 60 = 10 mins

t₂ = (10/55) 60

= 10 min 55 sec

Difference = 10 min 55 sec - 10 min

= 55 sec.

How much time will you save on a ten mile trip if you travel at 60mph rather than at 55mph?

Summary:

55 sec will be saved on a ten mile trip if you travel at 60 mph rather than at 55 mph.
