Answer:
car covers distance of 450 km in 4hr and 30min
4hr and 30 min - (4*60)+ 30 equal to 270
distance covered by car in one minute equal to 450/270 equal to 1.6 km
speed of car equal to (1.6*60)/60 equal to 1.6 km /hr
You multiply top and bottom of the fraction by the conjugate of 5 - √2 which is 5 + √2. This produces a rational denominator:-
= √7 ( 5 + √2) / (5 - √2)(5 + √2)
= √7 ( 5 + √2) / (25 -2)
= (√7 ( 5 + √2)) / 23 answer
