The best estimate for distance traveled?

Best estimate is usually da mean.

Mean of speed = (60 + 70)/2 = 65

Mean of time = (3 + 4)/2 = 3.5

Distance = Speed × Time

Distance = 3.5 × 65

Distance = 227.5 miles.

D) 210 miles is da closest, so answer is ' d '

Hope this helps

Feel free 2 email me if u have any more questions !

First you have to find a average for the rates. (60+70)/2 = 65 miles per hour Then find the average time (3+4)/2 = 3.5 hours Speed = distance/time So distance= speed * time =65 miles per hour/3.5 hours =227.5 miles

to find distance multiply together the rate and time

in this case 65 * 3 hr 30min (210min) = 13700 (approx.)

the answer would be B) 160miles

65x3.5=227.5 miles

God bless you.
