Car a is 30 miles ahead of car b car a is going 60 mph and car b is going 70 mph how long will it take car b to catch car a
frez [133]

Answer:

3 hours

Step-by-step explanation:

After one hour, car a will be only 20 miles ahead of car b, after two hours, car a will only be 10 miles ahead of car b, and after 3 hour, they will both be equal. This is because car b is going 10 mph faster than car a, because 70-60=10. every hour, car b will catch up to car a by 10 miles.

Give the rate in miles per hour. Round to the nearest tenth.<br> Rachel jogs 20 feet in 3 seconds.
Tanya [424]

Answer:

Rate of jogging is 4.6 miles per hour.

Step-by-step explanation:

Rachel jogs 20 feet in 3 seconds and we have to find the rate of jogging in miles per hour.

Since 1 feet = 0.000189394 miles

Therefore, 20 feet = 0.0037879 miles

Similarly, 1 second = \frac{1}{3600} hour

Therefor, 3 seconds = \frac{3}{3600}

                                  = \frac{1}{1200} hours

Formula to calculate the rate = \frac{\text{Total distance of jogging}}{\text{Time taken to cover the distance}}

                                                = \frac{0.0037879}{\frac{1}{1200} }                                                        

                                                = 1200 × 0.0037879

                                                = 4.545

                                                ≈ 4.6 miles per hour

Therefore, rate of jogging is 4.6 miles per hour.
