Answer

The equivalent rate when she earns $240 is 12 hours

Explanation

She earns $80 for every 4 hours she teaches a tennis lesson

Using this relationship

cost = rate x time

cost = $80

time = 4 hours

Now, we want to calculate the amount she earned per hour when she teaches a tennis lesson

80 = rate x 4

rate = 80/4

Rate = $20/hour

This implies that she earns $20 for every lesson she teaches one hour

If she earned $240 then the equivalent rate can be calculated as

Cost = rate x time

cost = $240

rate = $20/h

240 = 20 x time

time = 240 / 20

12 hours

Therefore, the equivalent rate when she earns $240 is 12 hours
