of 5 miles an hour faster than the first rate,
How many miles did Mr. Anderson drive during th
hours?

Answer 1

If you were asking how many miles in total: 290 miles.

If you were asking how many miles in the 2 hours: 122 miles

Explanation:

In the first 168 miles,

`Since \\v_1=168miles/3h=56 miles/h\\\\Thus  \\v_2=v_1+5=56+5=61miles/h\\\\X_1=168miles\\X_2=v_2*2h=61*2=122miles\\X_1+X_2=168+122=290miles\\\\`
