Step-by-step explanation:
simplify the product so (1) w mutiplied by w gives you w^2 . (2) 21 mutilplied by 21 gives you 441 . so now you would have 5( w^2 -441 ) (3) now you distribute 5 among the numbers so you should have 5w^2 -2205 .
drove 1h 45 min
break 15 min
drives 1h 20 min
1h 45min+1h 20 min+15min=3h 20min
3h 20 min=3 1/3h
3 1/3h*75 km/hr=<u>250 km</u>
