Best Answer

Remember Speed = distance / time

Algebraically rearrange

Time = Distance / Speed

Hence

Time = 2.5 miles/ 220 miles per hour

Divide the number and cancel down the 'miles'.

Time 0.01136 hours.

Multiply by '60' to convert to minutes.

time - 0.681818 minutes.

Multiply by '60' again to convert top seconds

time = 40.9090909... seconds.

Say 40.9 secs.
