Jim decided to go for a drive in his car. he started out at 0 miles per hour(mph). he then accelerated 20 mph down his street. then, to get on the highway he accelerated another 35 miles per hour. a car was going slow in front of him so he slowed down 11 mph. he then go off the highway, so he slowed down another 7 mph. at what speed was he driving?

37 mph

Step-by-step explanation:

if he starts at 0 then goes to 20 then add another 35 which gives you 55mph then he slows down you decrease 11 which is 44 then decrease again 7 gives you 37mph

could you reply to this with the question so i can ?

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
