Answer:
60 km
455 km
23 km
60 km
82.5 km
Explanation:
Time = t
Speed = s
Distance is given by
![d=s* t](https://img.qammunity.org/2022/formulas/mathematics/high-school/isyrp984n3v64omykrb02lxejloazwnu7l.png)
t = 2 hours
s = 30 km/h
![d=30* 2=60\ \text{km}](https://img.qammunity.org/2022/formulas/mathematics/high-school/svvli89ez2d7zbf3xx2c0otapt5f060j85.png)
Distance driven is 60 km.
t = 7 hours
s = 65 km/h
![d=65* 7=455\ \text{km}](https://img.qammunity.org/2022/formulas/mathematics/high-school/iacqgdjg6zxezhfpeou21h289chdzux4ay.png)
Distance driven is 455 km
t =
![(1)/(2)\ \text{hours}=0.5\ \text{hours}](https://img.qammunity.org/2022/formulas/mathematics/high-school/wzurqilcnhggm29b7jeyi5nqk02laj7xma.png)
s = 46 km/h
![d=46* 0.5=23\ \text{km}](https://img.qammunity.org/2022/formulas/mathematics/high-school/xwmzpmzal0rowm1abxz3kug5rq2lh512gc.png)
Distance driven is 23 km
t = 45 minutes =
![(45)/(60)=0.75\ \text{hours}](https://img.qammunity.org/2022/formulas/mathematics/high-school/9gbej7s1kj6mbe9x89zzwr36dmu5xk47nc.png)
s = 80 km/h
![d=80* 0.75=60\ \text{km}](https://img.qammunity.org/2022/formulas/mathematics/high-school/4cmyyt9v2y9zoywmop0iemx806c0msqpka.png)
Distance driven is 60 km
t =
![1(1)/(2)\ \text{hours}=1.5\ \text{hours}](https://img.qammunity.org/2022/formulas/mathematics/high-school/6wmmd8xx578crzcnm7uqt9z4hjzyfhz7yw.png)
s = 55 km/h
![d=55* 1.5=82.5\ \text{km}](https://img.qammunity.org/2022/formulas/mathematics/high-school/hj7jwdugks513lvogrt5xkai5baeft5y89.png)
The distance driven is 82.5 km
