Question

Mrs.Padre drives 2 hours at a n average speed of 35 miles per hour then she drives 3 hours at a speed of 48 miles per hour what is her average speed for the whole trip

Answer 1

She drove 2 hours at 35 miles per hour for a total of 35 * 2 = 70 miles.

She drove 3 hours at 48 miles per hour for a total of 48 * 3 = 144 miles.

Her total miles were: 70 + 144 = 214.

Her total driving time was 3 + 2 = 5 hours.

Divide her total miles by total time for her average speed:

214 / 5 = 42.8 miles per hour average speed.

Not sure if you need to round the answer or not.
