“Ms. Blanco drove her car at a speed of 80 kilometers per hour for 1 1/2 hours, then at a speed of 100 kilometers per hour for 2

lara31 [8.8K]

I’m pretty sure it’s 370 bc
1 and a half hours is 80+40 (40 is half of 80)
and 2 and a half hours, so 100 for each hour.
100+100+50= 250

250+120=370!!

answer : 370 kilometers per hour

At the beach this weekend, the ratio of sandcastles to kites was 3 to 5. If there were 15 kites spotted, how many items were see

Gelneren [198K]

Answer: 24

Step-by-step explanation:

The ratio of sandcastles to kites was 3 to 5 so if 15 kites were spotted that meant that the 5 was multiplied by 3 so then we multiply the 3 by 3. Now there are 9 sandcastles and 15 kites so now we add 9 to 15 to figure out how many items were seen in all. Nine added to 15 equals 24 which means that 24 items were seen in total.
