tom drove at a rate of 75mph for 3 hours. he stopped for lunch and then drove for another2 hours at the rate of 80mph. how many miles did tom drive?
Answer provided by our tutors
since speed = distance/time => distance = speed*time
the distance he drove before lunch for 3 hours + the distance he drove after lunch for 2 hours = total distance
75*3 + 2*80 = 385 miles
Tom drove 385 miles.
