Question

a dog runs 12 miles per hour select animals that run faster than the doglion 100 miles 2 hrsbear 60 miles in 2 hrszebra 80 miles in 2 hrselk 90 miles in 2 hrs

Answer 1

We were told that a dog runs 12 miles per hour.

If a lion runs 100 miles in 2 hours, it means that the number of miles that the lion runs per hour is 100/2 = 50 miles per hour

If a bear runs 60 miles in 2 hours, it means that the number of miles that the bear runs per hour is 60/2 = 30 miles per hour

If a zebra runs 80 miles in 2 hours, it means that the number of miles that the zebra runs per hour is 80/2 = 40 miles per hour

If an elk runs 90 miles in 2 hours, it means that the number of miles that the bear runs per hour is 90/2 = 45 miles per hour

We can see that all the other animals cover more miles per hour than the dog. Thus,they all run faster than the dog
