Answer:
The equation that relates the number of hours, h, with the speed, s, is: h = 240/s.
If he drives at 50 miles/h he'll make the trip in 4.8 h.
Step-by-step explanation:
The formula for the average speed is given by:
average speed = distance/time
Since Jack takes 6 h if he drives at 40 miles per hour, then the distance between Boston and Bangor must be:
distance = (average speed)*time
distance = 40*6 = 240 miles
The equation that relates the number of hours to the speed at which he makes the trip is:
h = 240/s
If he drives at a speed of 50 miles, he'll make the trip in:
h = 240/50 = 4.8 hours
