Chris and goffy ran from newton to boston at 15 km/h and 12 km/h respectively. they both started from newton at 10: 00 a. m. if goffy reached boston at 10: 30 a. m., at what time did chris reach boston ?

The Answer is 10:24 am because...

Chris=15km per hour

Goffy=12km per hour

So Goffy took 30 minutes Boston=6km from Newton. So Chris took 24 minutes and he got to Boston at 10:24 am

Hope this Helps you!      :)

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
