Plz william’s typical running speed is 6 km/h. the difference between his fastest speed and his typical speed is 1.5 km/h. the equation f-1.5=6 can be used to represent this problem, where f is william’s fastest speed. what is william’s fastest speed?

William's fastest speed is 7.5 km/h

Step-by-step explanation:

Let the fastest speed of William is f therefore from the question's statement the equation will be

f - 6 = 1.5

Here difference between William's fastest speed and typical speed is 1.5 km/h

Now we will add 6 on both sides of the equation

(f - 6) + 6 = 1.5 + 6

f = 7.5 km/h

So the fastest speed is 7.5 km/h

about 0.75 hours
