Complete Question

Alberta is going to have dinner at her grandmother's house, but she is running a bit behind schedule. As she gets onto the highway, she knows that she must exit the highway within 55 min if she is not going to arrive late. Her exit is 43 mi away. How much time would it take at the posted 60 mph speed?

Answer:

The time it would take at the given speed is
x = 43.00 \ minutes

Step-by-step explanation:

From the question we are told that

The time taken to exist the highway is
t = 55 min

The distance to the exist is
d = 43\ mi

Alberta speed is
v = 60 mph

The time it would take travelling at the given speed is mathematically represented as


t_z = (d)/(v)

substituting values


t_z = (43)/(60)


t_z = 0.71667\ hrs

Converting to minutes

1 hour = 60 minutes

So 0.71667 hours = x minutes

Therefore


x = 0.71667 * 60


x = 43.00 \ minutes
