On a trip over Thanksgiving Break Jenn's family has to drive a total of 325 miles.. If there are 126 miles to go and the car has
kherson [118]

The speed is 66.33 miles per hour

Step-by-step explanation:

Given

Total distance = 325 miles

They still have 126 miles to go. In order to find the distance they have covered, we will subtract the remaining miles from the total

So,

Distance\ covered=325-126=199\ miles

the car has been driving for 3 hours

So,

t= 3 hours

d = 199 miles

Speed=\frac{d}{t}\\=\frac{199}{3}\\=66.33\ miles\ per\ hour

The speed is 66.33 miles per hour
