It's 1: 00 p. m. and i've driven 120 miles. at 3: 00 p. m. i will have driven 208 miles. what is my speed?

From 1 pm to 3 pm is 2 hours.

208 miles - 120 mile = 88 miles

You drove 88 miles in 2 hours.

Speed = miles driven /  time driven:

88 / 2 = 44 miles per hour

44 miles/hour

Step-by-step explanation: since speed = distance/time

                                                                   = 88miles/2hours

                                                                   =44miles/hour

reduce the friction between its moving parts

step-by-step explanation:
