Answer:
The largest steep increase was from 1965 to 1966, while the second largest was from 1967 to 1968
Step-by-step explanation:
A) 1965 to 1966; number of accidents increased from 250 to 320.
Percentage increase = (320 - 250)/250 × 100% = 28%
B) 1967 to 1968; number of accidents increased from 300 to 370.
Percentage increase = (370 - 300)/300 × 100% = 23.33%
C) 1968 to 1969; number of accidents increased from 370 to 380.
Percentage increase = (380 - 370)/370 × 100% = 2.7%
D) 1969 to 1970; number of accidents increased from 380 to 410.
Percentage increase = (410 - 380)/380 × 100% = 7.89%
Thus;
The largest steep increase was from 1965 to 1966, while the second largest was from 1967 to 1968
