Answer:
45 km/h
Step-by-step explanation:
In the first part of the trip, he already covered 30 km so we can subtract that from the total distance
45 - 30 = 15
This means he has 15 km to go
He also took an hour, or 60 minutes, to get to school. We subtract the time spent of the first part and time spent talking to a friend from the 60 minutes
60 - 35 = 25
25 - 5 = 20
He took 20 minutes to cover the second part of the journey
Speed = distance/time
15/20 = 0.75
He covered 0.75 km per MINUTE
to find it in km/h, we just multiply the number by 60
0.75 x 60 = 45

Step-by-step explanation:
"In three years, Tonya will be 17."
14 + 3 = 17, so Tonya is 14 atm. (At The Moment)
"Tonya is twice Kevin's age." Kevin is 7, because 7 x 2 = 14.
"In another three years, Uncle Rob will be three times Tonya's age."
Since Tonya is 14, multiply 14 x 3 and you get 42.
If you're asking for the three years, 17 x 3 = 51 < Uncle Rob's age
Kevin is about 8 1/2 years old. Since 8 x 2 = 16, I multiplied 8 1/2 x 2 and got 17.
I hope this helped.

Answer:
Step-by-step explanation:
How to round off to the nearest degree
lets pick this number: 3,266.528
first let round to the nearest whole number by thousand
lets remove the .528 because we don’t need it
3,266
4000-3266 is 734
3,266 minus 3000 is 266
so rounded to the nearest thousand in the whole number is 3,000
or let’s say hundredths
3266.528
0.3- 0.28 is 0.3
0.28 - 0.2 is 0.8
so rounded to the nearest hundredth is 3,266.53
hope this helps :)
