Question

Oliver drove the first 90 miles of his journey in 1.5 hours and the remaining 120 miles in 3 hours. What was the total average speed?

Answer 1

90+120 miles/1.5+3 hours = 210 miles/4.5 hours = 46.67

Answer 2

Answer:

46.6666667

Step-by-step explanation:

we need to know the TOTAL average speed. To do that, we need to know how to get the speed, which is distance/time. Now we have to substitute. The equation we get is: s= (90+120)/(1.5+3). After solving, you should get s= (210miles)/(4.5hrs). Now all we have to do is divide, which equals 46.6666667.

Hope this helps! (:
