Rachel participated in a 12-kilometer walkathon to raise money for her favorite charity. If it took her 2.5 hours to complete it, what was the rate in kilometers per hour?

Step-by-step explanation:

here they gave 12 km are reached by 2.5 hours so we. should how much time they took for 1km

12/ 2.5 which is also 150min

12km which is also 12000

12000/150= 80m

it took 80m in 1min so

1hr = 60min

1hr x 80m

60x80

4800

convert it intlo km

4800/1000

4.8km

so it took 4.8 km for 1hour
